Signal Processing

Lucasfilm Home THX Ultra 2 Certification: This unit has been built and tested to conform to the high standards of sound and build quality set by the THX Ultra 2 Certification program. Home THX is the unique collaboration between Lucasfilm Ltd. and audio equipment manufacturers. THX Ultra 2 certification is currently the highest performance level, and provides a rigorous set of performance standards, along with proprietary surround sound post-processing technologies, designed to enhance the surround sound playback experience in the home theater. In addition to improvements to the power amplifier with respect to previous THX Ultra standards, two surround modes have been added: the THX Ultra 2 Cinema mode and the THX Music mode.

THX Ultra 2 Cinema Mode: This receiver is equipped with a "THX Cinema" mode that may be used to process movie soundtracks so they are heard as the movie directors intended them to be heard. All THX Select Certified receivers include Re-Equalization, Timbre Matching, Adaptive Decorrelation, Bass Management, Bass Peak Level Manager, and Loudspeaker Position Time Synchronization (delay).

THX Music Mode: This receiver is equipped with the THX Music mode which can be used for playing 5.1 multi-channel music sources. In this mode, new THX processing is applied to the surround channels to provide a wide stable rear soundstage.

THX Surround EX 7.1 Decoding: THX Surround EX soundtracks have an additional surround channel signal matrix encoded into the standard surround channel signals of a Dolby Digital soundtrack.  When a THX Surround EX soundtrack is decoded and played through a 7.1 channel system, you will hear more detailed imaging behind you; this feature brings more depth, spacious ambience and sound localization to the home theater experience than ever before.  Although THX Surround EX decoding produces the best results with soundtracks that have been recorded with THX Surround EX processing, the THX Surround EX 7.1 Decoding feature can be used, with varying results, with all 5.1 channel Dolby Digital, DTS or MPEG soundtracks.  THX Surround EX 7.1 playback requires a total of 4 surround speakers; one pair of surround speakers should be placed to the sides of the listening position, and the other pair of surround speakers are supposed to be placed behind the listening position.  The receiver is equipped with amplification for all 4 surround speakers.

• DTS-ES Discrete 6.1: Discrete 6.1 utilizes the digital discrete method to record all 6.1 channels, including the newly-added surround back channel, as independent channels. Since the surround left, surround right, and surround back channels are fully independent, sound can be freely designed and sound images can move freely and rapidly amongst each other within a background sound that envelopes the room from all sides.  
• DTS-ES Matrix 6.1: In the Matrix 6.1 format, the surround back channel is matrix encoded in advance to the surround left and surround right channels, and when a matrix decoder plays them back, they are decoded into separate surround left, surround right, and surround back channels.

DTS Neo:6 Surround: Featuring the newest DTS matrix processing technology, the DTS Neo:6 function provides up to 6.1-channel surround sound from conventional stereo sources, and can be used with virtually any 2-channel stereo source, analog or digital. Two modes are provided: Neo:6 Cinema is optimized for surround encoded stereo movie soundtracks, while Neo:6 Music mode is optimized for superior surround sound with stereo music sources.

DTS 96/24:  The AVR-5803 is compatible with sources recorded in DTS 96/24, a new multi-channel digital format. This new format can reproduce high-resolution, 5.1-channel audio on DTS-capable DVD players (those with DTS digital output), without the need for special players such as DVD-Audio or SACD. Some DVD-Audio discs will have a DTS 96/24 mix for compatibility with DVD-Video players.

Dolby Pro Logic II: Pro Logic II is a new Dolby Laboratories technology that produces surround sound from any stereo source, including CDs, VHS tapes, and TV programs. Like Dolby Digital, Dolby Pro Logic II has stereo surround output, giving you a more realistic surround sound experience. Unlike Dolby Digital, Dolby Pro Logic II allows you to enjoy a "5.1-like" presentation using any analog stereo source. Pro Logic II includes a Cinema mode, a Music mode, and an Emulation mode; the Emulation mode decodes audio in the same manner as original Pro Logic.

Dolby Headphone: This receiver includes the new Dolby Headphone signal processing mode. Extended headphone listening can cause fatigue, because all of the sound resonates inside the head. Dolby Headphone replicates speaker playback in a room and places the sound at the front or the sides, outside the head, to achieve sound resembling movie or home theaters. The Dolby Headphone mode is effective for both stereo and multi-channel audio sources. There are three levels of effect: DH1--Reference room (small room with weak reverberations), DH2--Live room (slightly stronger reverberations than DH1), and DH3--Large room (offering a sense of distance and sound diffusion effects). In addition to Dolby Headphone playback, the AVR-5803 can also output signals encoded in the Dolby Headphone mode from the recording output terminal to allow recording to another digital or analog recording device.

Features

Remote Control: The AVR-5803 is shipped with the Denon RC-8000 multibrand/learning touchscreen remote control system and the RC-8001ST RF charger/base station. A complete overview of the remote control system can be found in the "Remote Control" section below.

Chassis Construction: The AVR-5803 incorporates a chassis design in which the digital, analog audio, video, and control circuits are each isolated in their own blocks. These circuits are also individually shielded from the effects of transformer coils in the power section. The total chassis design preserves the purity of the audio signal from input to output to give your home theater a clean yet powerful sound, alive with all the details of the original recording.

Wide Range Circuit Topology: Front end and power amplifier circuitry is designed with flat frequency response that extends to 100 kHz, perfectly suited for next-generation wide range audio media such as SACD and DVD-Audio.

192kHz/24-bit Analog-to-Digital Conversion: The AVR-5803 is capable of 24-bit, 96kHz or 192kHz A/D conversion, which improves signal-to-noise and dynamic range by approximately 10dB. This A/D conversion and DSP processing can be done on external input signals (up to 7.1 channels), thus making it capable to perform bass management and delay processing of DVD-Audio signals. THX post processing is also possible with this DSP.

192kHz/24-bit Digital-to-Analog Conversion: Two Burr Brown linear PCM 192kHz/24-bit DACs are included for each channel, giving the AVR-5803 a total of 16. The 192kHz sampling and 24-bit word length capabilities of the DACs allows you to play high-resolution recordings and hear the increased clarity, detail and dynamic range of those recordings.

ALPHA 24 Processing: The AVR-5803 includes Denon's renowned 24-bit ALPHA processing technology that reproduces digital signals in a waveform with the smoothness of analog signals. This technology thoroughly suppresses annoying quantization distortion and faithfully reproduces the delicate musical details of low-level signals. ALPHA 24 processing works in 2-channel Stereo, Direct, Pure Direct modes.

DDSC-Digital (Dynamic Discrete Surround Circuit): DDSC-Digital is a circuit configuration specially designed by Denon in which all the elements of the surround processor are optimized by the use of selected high performance discrete elements, including separate A/D and D/A conversion, with sophisticated dual DSP surround decoding.

Dual 32-bit SHARC Processors: Featuring the newest Analog Devices 32-bit floating point HammerHead SHARC 21161 DSP devices, the AVR-5803 provides superb resolution and widest dynamic range of Dolby Digital, DTS and PCM audio signals.

192kHz/24-bit Digital Interface Receiver: The AVR-5803 employs a total of four 192kHz, 24-bit digital interface receivers, one for every two channels, enabling multi-channel digital input through the Denon Digital Link or external digital input to perform at optimum potential.

Fan Cooling: The receiver is fan cooled for reliable operation at high output levels. The fan is temperature and volume level sensitive, to minimize or prevent audible fan noise.

On-Screen Display (OSD): An OSD can be displayed on your television for easy system setup. The OSD is sent through the Monitor 1 S-video and composite video monitor outputs; the OSD is not sent through the component video output, the Monitor 2 S-video output or the Monitor 2 composite video monitor output.

7.1 Multi-Channel Inputs: The AVR-5803 is equipped with two 7.1-channel inputs to accommodate present and future multi-channel formats, such as DVD-Audio.

RS-232C Port: The AVR-5803 includes an RS-232C port for connection to external whole-house control systems, from companies such as AMX, Crestron, and others, and provides a software/firmware upgrade pathway.

IEEE 1394 Expansion: The back panel and circuitry are ready for the addition of an IEEE 1394 port. IEEE 1394, also known as "i.LINK", is a high speed digital interface that may be used for plug and play connection of compatible digital components. 

Multi-Zone Output: The AVR-5803 provides a Multi-Zone Output function and a Select function that let you output different sources to multiple zones. Sources can be selected for output to up to 2 additional zones, in addition to the main room. Multi-room Zone 1 can have variable pre-amp output along with a composite video feed, and Multi-room Zone 2 can have a fixed stereo audio pre-amp output. The AVR-5803's Power Amplifier Assign function lets you assign the 2 Surround Back (SB L/R) amplifier channels to instead drive the Multi-room Zone 2 powered speaker outputs, with 170 Watts per channel power output capability, while still providing 5 full amplifier channels to drive the main and surround speakers in the home theater room.

Dual Surround Speaker Mode: The AVR-5803 provides the ability to connect two different sets of surround speakers, and place them in the appropriate locations in your home theater room, so that you can enjoy both movie soundtracks and music listening, with optimum results and no compromise.

Surround Modes: In addition to straight Dolby Digital, Dolby Pro Logic, and DTS playback, you can choose from the following modes:

• THX Surround EX: THX Surround EX soundtracks have an additional surround channel signal matrix encoded into the standard surround channel signals of a Dolby Digital soundtrack. By adding a surround back channel, this mode gives you more detailed imaging behind you, allowing for 360-degree surround sound effects.
• Dolby Digital EX: This mode is optimized for playing sources recorded in Dolby Digital Surround EX. These sources are very similar to the THX Surround EX sources, but without THX certification.
• DTS ES Discrete 6.1 and DTS ES Matrix 6.1: DTS ES Matrix 6.1 performs matrix decoding to create a rear center speaker. DTS ES Discrete 6.1 features digital discrete recording of all channels including the surround back channel.
• THX Discrete 6.1 and THX Matrix 6.1: This mode offers an alternative for sources recorded in DTS-ES, sometimes resulting in a more natural sound. 
• THX Ultra 2 Cinema: This mode applies processing (Re-Equalization, Adaptive Decorrelation, Timbre Matching, etc.) to recreate the exact sound the movie director intended you to hear.
• THX Music Mode: This mode is for playing back 5.1-channel music sources in 7.1 channels.
• DTS 96/24: You can select this mode for playing DTS-encoded 5.1-channel music sources if you don't have back surround channels.
• DTS NEO:6: Allows you to choose Neo:6 Cinema mode, which is optimized for surround encoded stereo movie soundtracks, or Neo:6 Music mode, which is optimized for superior surround sound with stereo music sources.
• Dolby Pro Logic II: This mode gives you 5.1-like sound from 2-channel music and movie sources.
• Wide Screen: Select this to achieve an atmosphere like that of a movie theater with a large screen. In this mode, all signal sources are played in the 7.1-channel mode, including Dolby Pro Logic and Dolby Digital 5.1-channel sources. Effects simulating the multi- surround speakers of movie theaters are added to the surround channels.
• Super Stadium: Select this when watching baseball or soccer programs to achieve a sound as if you were actually at the stadium. This mode provides the longest reverberation signals.
• Rock Arena: Use this mode to achieve the feeling of a live concert in an arena with reflected sounds coming from all directions
• Jazz Club: This mode creates the sound field of a live house with a low ceiling and hard walls. This mode gives jazz a very vivid realism.
• Classic Concert: Select this for the sound of a concert hall rich in reverberations
• Mono Movie: Select this when watching monaural movies for a greater sense of expansion
• Matrix: Select this to emphasize the sense of expansion for music sources recorded in stereo
• 5Ch/7Ch Stereo: The front left channel signals are output to the surround and surround back signal left channels, the front right channel signals are output to the surround and surround back signal right channels, and the in-phase component of the left and right channels is output to the center channel. Use this mode to enjoy stereo sound.

Personal Memory Plus: The Personal Memory Plus function automatically memorizes the surround modes and input modes selected for the different input sources. When an input source is selected, the modes stored in memory for that source are automatically recalled. The surround parameters, tone control settings and playback level balance for the different output channels are memorized for each surround mode.

Pure Direct Mode: In addition to surround sound playback, the AVR-5803 lets you enjoy pure 2-channel stereo sound as well through its Pure Direct mode. In Pure Direct mode, power to the video circuitry and the front panel display is turned off, and during analog input, power to the digital circuitry is also automatically turned off. Furthermore, during 2-channel linear PCM input, the D/A converter section is re-configured to 8 DAC dual-differential operation (4 DAC channels for each audio channel) to provide optimum D/A conversion of 2-channel PCM sound sources, such as CD with the highest transparency and widest dynamic range.

Bass Management and Speaker Setup: Various speaker size settings are available to ensure that small speakers do not receive full-range signals and to tell the receiver where to send signals.

• Front Speakers: The front speaker size may be set to "Large" or "Small"
• Center Speaker: If you have selected "Large" as the front speaker size, the center speaker may be set to "Large", "Small" or "None". If you have selected "Small" as the front speaker size, the center speaker may be set to "Small" or "None".
• Subwoofer: You may select "Yes" or "No"
• Surround Speakers A: If you have selected "Large" as the front speaker size, the surround speakers A may be set to "Large", "Small" or "None". If you have selected "Small" as the front speaker size, the surround speakers A may be set to "Small" or "None". Note: If you have selected "None" as the surround speakers A size, the surround speakers B and surround back speakers are automatically set to "None".
• Surround Speakers B: If you have selected "Large" as the front speaker size, the surround speakers B may be set to "Large", "Small" or "None". If you have selected "Small" as the front speaker size, the surround speakers B may be set to "Small" or "None".
• Surround Back Speakers: If you have selected "Large" as the front speaker size and either the surround speakers A or surround speakers B are set to "Large", the surround back speakers may be set to "Large", "Small" or "None". If you have selected "Small" as the front speaker size, the surround back speakers may be set to "Small" or "None". If the surround back speaker size is set to "Small", you may set the number of surround back speakers to 1 or 2.
• Subwoofer Crossover Frequency: The frequency of the low pass filter on the subwoofer output can be set to a fixed (80Hz THX setting) or variable output according to the speaker's bass playback ability (selectable between 40, 60, 80, 100, or 120Hz). In addition to these settings, if you are using a THX Ultra 2 certified subwoofer, you can select the "Boundary Gain Compensation." The Boundary Gain Compensation allows the subwoofer to receive very low frequencies (20-55Hz). If the bass seems too strong, the compensation can be set to "on" to cut the lower frequencies.
• Delay Time: The delay time (distance from speaker to listening position) for each channel can be adjusted from 0 to 60 feet in 0.1 foot increments.
• Test Tone: The test tone feature allows you to independently adjust the volume level of each channel
• Bass Peak Level: The bass peak level may be set to prevent distortion and possible damage to your subwoofer

Re-Equalization: The tonal balance of a film soundtrack will be excessively bright and harsh when played back over audio equipment in the home because film soundtracks are designed to be played back in large movie theaters using very different professional equipment. Re-Equalization restores the correct tonal balance for watching a movie soundtrack in a small home environment.

Timbre Matching: The human ear changes our perception of a sound depending on the direction from which the sound is coming. In a movie theater, there is an array of surround speakers so that the surround information is all around you. In a home theater, only two speakers located to the side of your head are used. The Timbre Matching feature filters the information going to the surround speakers so that they more closely match the tonal characteristics of the sound coming from the front speakers. This ensures seamless panning between the front and surround speakers.

Adaptive Decorrelation: In a movie theater, a large number of surround speakers help create an enveloping surround sound experience, while in a home theater there are usually only two speakers. This can make the surround speakers sound like headphones that lack spaciousness. The surround sounds will also collapse into the closest speaker as you move away from the middle seating position. Adaptive Decorrelation slightly changes one surround channel's time and phase relationship with respect to the other surround channel. This expands the listening position and creates, with only two speakers, the same spacious surround experience as in a movie theater.

CINEMA EQ. (Cinema Equalizer): The Cinema EQ function gently decreases the level of the extreme high frequencies, compensating for overly-bright sounding motion picture soundtracks. Select this function if the sound from the front speakers is too bright. This function only works in the Dolby Pro Logic II, Dolby Digital, DTS Surround, DTS Neo:6, and Wide Screen modes.

D.COMP. (Dynamic Range Compression): Motion picture soundtracks have tremendous dynamic range (the contrast between very soft and very loud sounds). For listening late at night, or whenever the maximum sound level is lower than usual, the Dynamic Range Compression allows you to hear all of the sounds in the soundtrack (but with reduced dynamic range). This only works when playing program sources recorded in Dolby Digital or DTS. You can select one of the four settings: "OFF", "LOW", "MID" (middle), or "HI" (high). 

Surround Parameters: You can adjust the following surround mode parameters:

• Effect: This parameter turns the effect signals with multi-surround mode speaker effects on and off in the Wide Screen mode. When this parameter is turned off, the surround back left and surround back right channel signals are equivalent to the surround left and surround right channels, respectively.
• Level: This parameter sets the strength of the effect signals in the Wide Screen mode. It can be set in 15 steps, from "1" to "15". Set this to a low level if the positioning or phase of the surround signals sounds unnatural.
• SB Ch Out: This indicates whether or not you are using the surround back speakers.
• Room Size: This sets the size of the sound field. There are five settings: "Small", "Med.S" (medium-small), "Medium", "Med.L" (medium-large) and "Large".
• Effect Level: This sets the strength of the surround effect. The level can be set in 15 steps from 1 to 15.
• Delay Time: In the matrix mode only, the delay time can be set within the range of 0 to 200 ms
• Tone Control: This can be set individually for the separate surround modes other than Direct and Home THX Cinema

Dialogue Normalization: The dialogue normalization function is activated automatically when playing Dolby Digital program sources. Dialogue normalization is a basic function of Dolby Digital, which automatically normalizes the dialog level (standard level) of the signals that are recorded at different levels for different program sources, such as DVD, DTV and other future formats that will use Dolby Digital. 

Assignable Digital Inputs: The 11 digital inputs (6 optical and 5 coaxial) can be assigned to the individual input sources (Example: Optical 1: CD, Optical 2: DVD, etc). Optical inputs 5 and 6 are equipped with an optical digital output jack that can be used for digital recording between a digital audio source and a digital audio recorder. There is also a Coaxial Digital RF input jack for a laserdisc player that have a Dolby Digital RF output.

Component Video Switching: In addition to composite and S-Video switching, this unit can switch between three component video sources. There are 3 component video inputs and 1 component video output; each input and output has gold-plated jacks labeled "Y", "Pb/Cb" and "Pr/Cr". This feature allows you to connect, and switch between, high resolution video sources equipped with component video outputs. High performance relays provide wideband component video bandwidth (>50 MHz), compatible with progressive DVD (480p), as well as HDTV formats (720p, 1080i).

Upconverting Video Signals: The AVR-5803 is equipped with a video switching system that converts composite video signals to S-Video and/or composite and S-Video to component video. The input signal types--whether composite, S-Video or component--are auto detected, then the signal with the highest picture quality is given highest priority and output to the monitor.

Denon Link: The RJ-45 jack on the back panel allows the connection of a Denon DVD player (with Denon Link output) for ultra-clean digital transfer. The Denon Link interface enables the transfer of high-grade linear PCM 24-bit, 96kHz, 6-channel audio or 24-bit, 192kHz, 2-channel audio via a shielded twisted pair cable. (If the 24-bit 192kHz sound source is copyright protected, the DVD player may convert the digital output to a 24-bit, 48kHz signal). Since Denon Link uses low-voltage differential signaling (LVDS), transfer capabilities of greater than 1.2 Gbps at a differential voltage of approximately 0.3 Vpp are possible. Since the signal transfer is balanced and voltage is lower than coaxial or unbalanced cables, the Denon Link is far less susceptible to radiated noise, ensuring the highest level of signal transfer. Note: Presently, the only Denon DVD player with the Denon Link is the DVD-9000. 

Last Function Memory: This unit is equipped with a last function memory, which stores the input and output setting conditions as they were immediately before the power was switched off. 

Back-Up Memory: The unit is also equipped with a back-up memory. This function provides approximately one week of memory storage when the main unit's power switch is off and with the power cord disconnected.

Remote Control

Multibrand/Learning RF Remote: The RC-8000 has controls for an entire home theater system as icons on a backlit LCD touch screen. You can navigate and make selections by touching the screen directly. In addition to being pre-programmed to control many brands of audio/video source components and TVs, this remote also has learning capability, allowing it to be customized for any installation. When the RC-8000 is used in combination with the RC-8001ST charger base station, the RC-8000 can communicate with the receiver via a powerful RF (radio frequency) signal, allowing you to operate your system from another room. Note: You can choose from 2 different RF bands, and use dedicated ID codes to distinguish among multiple RC-8001ST charger base stations.

Editing Functions, for Easy Customization: You can program the RC-8000 to control up to 23 different components. You can provide each button with a unique label indicating the command you have assigned it. You can change the assignments at any time, or add new buttons and delete old ones, to make the RC-8000 work exactly the way you want it to.

Independent Buttons: Independent buttons have been provided on the main unit for frequently-used operations, such as volume control, channel selection, muting, and backlighting activation.

System Call: Up to 20 System Call settings (a programmed series of 10 sequentially-issued commands) can be stored. The System Call programs you have stored can be easily be checked on the LCD panel.

User Backup: This function lets you back up your customized settings in the controller's built-in flash memory, to protect your customized settings and learned commands from memory loss due to battery exhaustion.

USB Support: The RC-8000 includes a USB port that lets you connect it to a PC where you can back up settings or do editing work. 

Auto Power Off: To conserve battery power, the Auto Power Off function automatically blanks the LCD screen after a certain period of time elapses. This time period can also be easily customized, as can the backlighting time.

RC-8001ST Charger Base Station: The RC-8001ST is equipped with a wired data output terminal as well as an IR emitter terminal. This wired data output can be connected directly to the AVR-5803 or to the data input port of a Denon RC-616 IR re-transmitter. In addition, you can connect an IR supplemental emitter, such as Denon's RC-618, or other IR emitter types. The RC-8001ST also provides a battery charging function. The Ni-Cad battery pack that comes with the RC-8001ST is inserted into the RC-8000, and you can charge the batteries in the RC-8000 by simply placing it onto the RC-8001ST charger base station. The excessive charge prevention function prolongs the Ni-Cad battery life, even if the RC-8000 is left in the charger base station for an extended period. The charger base station has the following dimensions: W=5.146", H=1.685" (8.294" with the antenna extended), D=6.303".
